Eating to Fight the Climate Crisis
The EAT-Lancet Commission lays out the best diet for human and planetary health.
“Scientists have a moral obligation to clearly warn humanity of any catastrophic threat and to ‘tell it like it is.’” In November 2019, more than 11,000 scientists from 150 countries declared “clearly and unequivocally that planet Earth is facing a climate emergency.” As you can see in a series of graphs starting at 0:33 in my video Win-Win Dietary Solutions to the Climate Crisis, CO2 levels are rising and the glaciers are melting, as is Antarctica. The oceans are getting hotter, and more acidic. Sea levels are rising, and extreme weather events are escalating. Yes, the use of fossil fuels is going up, for air travel, for example, but so is per capita meat consumption. In fact, one of the solutions offered by scientists to help the climate crisis is “eating mostly plant-based foods while reducing the global consumption of animal products….”
What makes “designing a sustainable diet” so easy is that “the dietary advice is the same: eat less meat.” It’s good for our personal health (by reducing the risk of our number one killer, for instance), as well as planetary health. As you can see below and at 1:24 in my video, the least healthy foods also cause the worst environmental impact.
Indeed, the foods with the most nutrition just so happen to be the foods that cause the lowest greenhouse gas emissions, as shown below and at 1:31 in my video, so the effect is a win-win.
Let’s put it all together. If we are to “redesign the global food system for human and planetary health,” which is to say human health, planetary health, and future human health, what would it look like? Enter the EAT-Lancet Commission. What was the “result of more than 2 years of collaboration between 37 experts from 16 countries”? Suggesting a cut in total meat consumption down to no more than an ounce a day (28 g), which is around the weight of a single chicken nugget, and, concurrently, a dramatic increase in our intakes of legumes (beans, split peas, chickpeas, and lentils), vegetables, nuts, and fruits. We aren’t only in a climate crisis, but a health crisis, too. “Unhealthy diets pose a greater risk to morbidity and mortality than does unsafe sex, and alcohol, drug, and tobacco use combined.” But we can address both crises at the same time by “increasing consumption of plant-based foods and substantially reducing our consumption of animal source foods.”
